05/22/2020 UPDATE. The IPS 240hz monitor tier list.(I've measured/tried the all) and my honest explanation why.

[ballzley]

I got a question... which one is the better choice and does even matter? XB273 Gxbmiipprzx and XB273 Xbmiprzx seem to have the same specs besides the ports or am i blind and missing another difference. My friend just order the XB273 Gxbmiipprzx because it was in stock at Walmart for 370$ plus tax and I see that the Xbmiprzx model is 500$ on amazon wonder if theirs a difference in performance between the both models.

Both are 1080p 27" 240hz monitors
XB273 Xbmiprzx is G-Sync, presumably module https://www.acer.com/ac/en/US/content/p ... .HX3AA.X02
XB273 Gxbmiipprzx is G-sync Compatible https://www.acer.com/ac/en/US/content/p ... .HX3AA.X03

Is the VG259QM still a decent monitor if you set it to 240@80 on games you dont get over 240fps on? Some games i do get 280 fps easy and some like warzone, i dont. Thanks

If you use Gsync/Freesync and your fps fluctuates sub 240hz you should stick to OD60 because OD80 becomes borderline usable sub 220hz due to overshoot.

If you play without a fixed refresh rate of 240hz with no Adaptive Sync, OD80 is usable with some minor overshoot (more than on the MAG251R), if you use ELMB-Sync at this refresh rate you eliminate a good % of corona artifact and you noticeably improve motion clarity.

OD80 is more suited for 280hz.

Thanks for the advice, one more thing not sure if you already mentioned this before but, i heard adaptivesync/ gsync/ freesync does give a tiny bit of input lag compared when its off.
2. is it best to leave it at 280hz no adaptivesync / no gsync and no elmb, if ur fps is fluatuating between 220fps - 280fps.if so is it best to leave it at OD 80 or OD 60 like you suggest, cause fps is fluatuating between 220hz - 280hz. not sure to cap it at 240hz or just leave it at 280hz since is able to reach that 280fps at certain parts in the game.
^ since OD 60 is best use for below 240fps and OD 80 best use for 265fps - 280fps above. if fps is always between 220fps- 280fps.
thanks in advance and stay safe

Thanks, one more question have you tried the VG259QM with just ELMB with no adaptive sync? people have mentioned that its better than ELMB-SYNC for certain situations. Will you be posting the g2g numbers in your part 3 review for the VG259QM?

Just so im understanding you correctly on a fixed refresh rate 240@80 is ok, with minor overshoot? and elmb can be enabled for better motion clarity? How much does respone time suffer on 60 OD in oppose to 80? Is the minor overshoot worth it for a better responce time? Sorry im not expert but id like to know as i play games competively.

On tftcentral there is a review on the VG279QM and the best g2g average and suggested setting to use is 240@80 which gives a responce time of 4.2 (best mode to use "hardware unboxed" claims). I understand the VG279QM & VG259QM use different panels? So i guess my question is do you have the numbers? how different is the 27 inch version from the VG259QM? I dont know the numbers etc for the VG259QM but im assuming at 240@60 response times dont suffer enough to not use it over 240@80? Thanks

Strobe duration with ELMB-Sync lasts 2.4ms compared to 1.2ms from standard ELMB, considering the VG259QM G2G average you will notice that ELMB-Sync tends to remove motion blur more effectively due to the strobe phase covering a bigger portion of the pixel transition.

This monitor can strobe at both 240 and 280hz if you don't use Adaptive Sync, the issue with ELMB/ELMB-Sync is that the overdrive is stuck at 80 over the entire refresh rate, this is perfectly fine if you are playing with VRR in the 180-280hz, however if you are strobing at 144hz with ELMB Sync it will cause some noticeable overshoot.

Yes, 240hz@80 is usable with some minor overshoot, ELMB-Sync can be enabled (for example with a 237fps CAP).

Idk why but me and some other VG259QM owners all agree on OD60 being more consistent for our aim accuracy, there's not much difference between OD60 and OD80 response time, the only difference is a slight improvement in motion clarity, both settings are perfectly usable for competitive gaming.

It's difficult to compare the VG279QM with the VG259QM, there hasn't been a single VG259QM review that shows g2g.
The VG259QM is much more similar to the AW2521hf(same panel) than the VG279QM, the overdrive behaviour on the VG279QM is completely different, 240hz OD80 on the VG279QM is basically the same as OD60 on the VG259QM.

I don't notice any difference in terms of input lag with Adaptive sync ON vs OFF.

Since it's impossible for me to constantly output 280hz I simply set a 270/275fps cap with ELMB-Sync to get a flawless experience in the 220-280hz range.

OD60 is not bad at 280hz, however there's no point in using OD60 since OD80 has less overshoot at 280hz than at 240hz while slightly increasing motion clarity.
Stick to OD80.

In Europe we only have available the Acer predator xb273gx model and not the xb273x model, so by buying the gx version is there any compromise on motion clarity or response times?

Another delay since the MSI MAG251RX and dell alienware aw2521HF are being retested. The UFO test and g2g results i had gotten, the color temperature wasn't at the correct setting since i tweak the rgb temperature setting to get accurate colors(even though there's already calibration software on windows). and because of that, the response times is considered invalid since i measured these monitors when they are "Colder than usual" which means slower response times.

The MSI is CLOSING in on the predator xb273x for the title of the fastest IPS monitor when it comes to response times based off my findings. It's VERY CLOSE. i will post the quintuple review very very soon(in a day or two) , i'm almost finished.

pop quiz, two UFO tests, which one is the MSI MAG251rx and which one is the acer predator xb273x?



now that IPS is out of the way.... Here are some photos to see what my future plans are.

That's not true. I've been waiting for this particular monitor to show up, and it's already in Europe, Acer confirmed that, I messaged them. Deliveries in Poland will start within a week, two Polish stores already taking pre-orders for XB273X. Perhaps you should just wait a little longer

Thanks for the info, out of curiosity can you tell me (somehow), how much did you pay for it?

Thank you!

I haven't ordered it yet, waiting for the general availability, but pre-order price is 2499 PLN, which is about 630 dollars/560 euro at the moment. Typically, new stuff here is quite expensive for some time, I expect the price to drop after it's in stock everywhere.
